IMS HP Load utility

IMS HP Load provides high performance reload processing for databases. The utility is a performance replacement of the IMS HD Reorganization Reload utility (DFSURGL0). The IMS HP Load utility supports various database organizations. It creates the indirect list data set (ILDS) of a HALDB that is compatible with the one created by IMS standard IMS HD Reorganization Reload utility. Also, the utility provides reports that contain statistics about space use and segment pointers.

Load API

IMS HP Load provides the Load application programming interface (Load API). By using the Load API, you can run the initial load process much faster than that of IMS DL/I.

Physical Sequence Sort for Reload

The utility sorts an unloaded database data set that is produced for an HDAM database to reduce the elapsed time required to reload the database. It also sorts an unloaded database data set for HDAM, PHDAM, HIDAM, PHIDAM, HISAM or SHISAM databases. The utility also provides reports, for use in the tuning analysis of the randomizing parameters.

Bitmap Resetter

The Bitmap Resetter utility can be used to adjust the bitmap of an HDAM, HIDAM, PHDAM or PHIDAM database to accommodate denser packing of the database blocks.
